4. Operating Instructions

For optimal performance and longevity of your new Li-ion battery, follow these initial operating guidelines:

• Initial Cycles: A new Li-ion battery will achieve its best performance after 2 or 3 complete cycles of charge and discharge. This means fully charging the battery to 100% and then allowing it to discharge completely until the phone powers off, repeating this process a few times.
• Regular Charging: After the initial cycles, it is generally recommended to keep Li-ion batteries charged between 20% and 80% for maximum lifespan, avoiding frequent full discharges or prolonged periods at 100% charge.

5. Maintenance

Proper maintenance can extend the life of your battery:

• Avoid exposing your phone to extreme heat or cold, as this can degrade battery performance.
• Use only compatible and certified chargers and cables.
• If storing the device for an extended period, ensure the battery is charged to approximately 50% to prevent deep discharge.

6. Troubleshooting

If you encounter issues after battery replacement, consider the following:

• Phone Not Powering On: Double-check all internal connections, especially the battery connector, to ensure they are securely seated.
• Battery Not Charging / Stuck at Low Percentage:
  • Ensure the battery flex cable is properly connected to the motherboard. A loose connection can cause incorrect charge readings or prevent charging.
  • Try a different charging cable and adapter to rule out external issues.
  • Perform a soft reset of your phone (refer to your phone's manual for instructions).
• No Fast Charging:
  • Verify that your charger and cable support fast charging and are functioning correctly.
  • Ensure your phone's software is up to date.
• Rapid Battery Drain:
  • Check background apps and usage patterns.
  • Ensure the battery is fully calibrated after the initial 2-3 charge/discharge cycles.

If problems persist after attempting these troubleshooting steps, please contact SwarKing customer support.
